Emlimny Medium Size Faraday Bag for Key Fob(2 Pack), Faraday Cage Protector, Car RFID Signal Blocking Key Fob Protector, Double-Layers of Shielding Carbon Fiber Material Anti-Theft Faraday Pouch

It works! I keep one attached to my purse car transponder, but for convenience only put the transponder in it when in an "iffy" situation, e.g., crowds, uncomfortable areas. Keep the backup transponder in one at home.

I don't review very often, but this is a great item. Nice quality and WORKS! You do have to put your fab in the back pocket but your car will not start unless you take it out. Amazing.

Works as advertised. Just be sure to put your device in the inside pocket of the pouch to block the signal.

Fits nicely in purse or pocket. Chain inside to hold key fob, and an additional one to clip in purse or on belt loop.

It's a scary world out there and we can't have too much security. Love the protection these key fob packs provide by preventing signals stealers.

Works as advertised. Eliminates communication from key fob to car when not in use, saving both fob and car battery.

Easy to carry just the right size. Easy to find in my purse. Would purchase again and recommend to friends and family

Well constructed but a bit too large to keep in a pants picket . Plenty of room for key fob , fits easily in small purse .

These do not work. I placed the key fob inside of it, completely closed it, and was standing over thirty feet away. Christ down on the bag through to the fob.In the car still started. Also stood near the car and could unlock the doors because the remote was still transmitting through these. Just doesn't work. These also look like they come from the dollar tree

fob still unlocks car from inside this bag. doesnt work
